Brief description
Fig. 1 is the overall structure diagram of this utility model embodiment；
Fig. 2 is the fixing schematic diagram of connecting rod of the present utility model.
Specific embodiment
In order that the purpose of this utility model and advantage become more apparent, with reference to embodiments this utility model is entered
Row further describes.It should be appreciated that specific embodiment described herein is only in order to explain this utility model, and without
In restriction this utility model.
As depicted in figs. 1 and 2, this utility model embodiment provides a kind of piston rod riveting die, including Pneumatic pressure
Bed 11, sleeve 2, connecting rod 6 and piston 3, described pneumatic press machine 11 is arranged at the left side of sleeve 2, on the push rod on pneumatic press machine 11
It is provided with a piston pin 13, sleeve 2 is in that cylindrical structural is arranged, and upper end seals, lower ending opening, the outer wall in sleeve 2 left side is provided with
One through hole 1, piston 3 is arranged in this sleeve 2 from top to down, and the size of piston 3 is matched with the size within sleeve 2, piston 3
Upper surface offset with the bottom surface within sleeve 2, piston 3 both sides are equipped with a pin-and-hole 5, the through hole 1 in pin-and-hole 5 and sleeve 2 left side
It is oppositely arranged, the size of through hole 1 is identical with the size of pin-and-hole 5.
In the present embodiment, outer wall lower end right angle setting one fix bar 8 in described sleeve 2 left side, fixing peace in the middle of fix bar 8
Fill a baffle plate 12, in the middle of baffle plate 12, be provided with a location hole 14, location hole 14 is rectangle structure setting, location hole 14 and piston 3
It is oppositely arranged, one end that baffle plate 12 is located at location hole 14 is provided with a screw hole 16, and screw hole 16 internal messing connects a screw rod 7, spiral shell
Bar 7 one end extends in location hole 14, and fixedly mounts a briquetting 15, and the other end extends to extraneous fixed installation one spill spin block,
Connecting rod 6 is to lower and upper this location hole 14 of insertion, and is compressed by briquetting 15；The aperture of described connecting rod 6 upper end extends to piston 2
Interior and parallel with the pin-and-hole 5 on piston 2.
In the present embodiment, described piston pin 13 right side passes through the pin-and-hole 5 on the through hole 1 and piston 3 in sleeve 2 left side, extends
Little in the hole to connecting rod 6；Described sleeve 2 is made up of metal material, increased the service life of sleeve 2.
